HJR 1 Homestead-Exemption Tax-Base Exposure

Jefferson County . 2025 final assessment roll

Snapshot

The Jefferson County read

Jefferson County fits the Agricultural / Rural Land archetype: a large share of land and some value sits in agricultural use, assessed at use-value far below market and classified as non-homestead, while the incorporated footprint is small relative to the county’s overall extent. At full phase-in in 2028, 35.1% of the county’s non-school taxable base is removed by the amendment, stepping up from 25.0% at the 2027 threshold. The exposure dynamic here is driven by the small residential core, which can carry high homestead concentration even though the surrounding agricultural land contributes little taxable value to begin with — the ag land is not the problem, but it also is not the cushion it might appear to be. Jefferson County ranks 19th of 67 counties by exposure.

Of 4,713 residential housing units, 63.5% are owner-occupied, 5.7% are owned by out-of-state owners, and 30.7% are non-homestead but Florida-owned. The out-of-state ownership share is not elevated here; the non-homestead residential segment is largely a local Florida-owned rental market, not an absentee-ownership story.

Land-use composition

Per-parcel out-of-state ownership data by land-use category is not available in this payload, so the composition table shows share of value only.

What the exposure band means

Band: High exposure. A large share of the base shifts. Diversification is the multi-year strategy; near-term, expect pressure to raise millage to hold services flat.

Looking ahead

Neither of the following changes the exposure figure above; both shape how Jefferson County grows its base after the amendment takes effect.

First, beginning January 1, 2027, the annual assessment-increase cap on non-homestead property drops from 10% to 5%, covering commercial and industrial real property and small residential rentals of nine units or fewer. Because a capped property’s assessed value can rise only 5% per year, the primary engine of base growth in these categories becomes transactions — a sale or change of control resets the property to market value — so transaction velocity matters more to non-homestead base growth than it did under the old cap.

Second, new Florida residents who did not maintain a Florida permanent residence as of December 31, 2026 phase into the larger exemption over five years rather than receiving it immediately. This residency ramp cannot be read from the assessment roll, so all exposure figures here assume full application of the exemption. Near-term exposure could run slightly lower than modeled in places with a meaningful share of recent arrivals still inside their five-year window.

Where the opportunity is

These recommendations are based solely on the tax roll’s land-use composition. They do not account for whether local land development regulations and zoning permit any of these uses, whether there is local obstruction, or the political dynamics that typically decide what actually gets approved. This is a starting point for a conversation, not a development plan.

• The first and most important point about Jefferson County’s composition is that agricultural land is a land bank, not a revenue base. Its fiscal contribution is small by design — 57.0% of just value sits in ag, but that value is assessed at use-value, not market, and it generates little taxable base. Mitigation work belongs in the built core, not on the farm.
• Commercial property represents only 2.1% of just value, making it the single biggest lever available. Building a taxable, non-homestead commercial spine in the town center — along existing corridors and arterial frontage — is the most direct path to deepening the base in a category the amendment does not touch. Even modest commercial growth in a county this lightly developed on the commercial side produces outsized relative gains.
• The county’s agricultural economy itself is an underutilized asset for base-building. Agricultural-processing facilities, agritourism operations, and value-added production facilities convert the ag economy into taxable commercial and industrial property. These uses sit on land already in agricultural ownership and can be developed without requiring large-scale land-use conversion.
• When agricultural land does convert, the direction of that conversion matters enormously fiscally. Steering converting parcels toward commercial, industrial, or mixed-use adds more durable, non-homestead taxable base than residential subdivision does. The 3.6% of value sitting in Other/Vacant parcels represents near-term opportunity if those parcels are positioned for commercial or industrial use rather than single-family development.

Watch-out: converting agricultural land straight to single-family subdivision is the worst fiscal outcome under the amendment. It removes a low-cost land use and replaces it with the most-exempted, highest-service category on the roll. Every acre that converts to owner-occupied homestead housing deepens the exposure problem rather than solving it.

Source and scope

All figures are drawn from the Florida Department of Revenue 2025 final assessment roll, the most recent certified roll in the state’s possession. The roll is used here as a structural proxy for tax-base composition, not as a dollar forecast for any specific budget year. HJR 1 / CS-HJR 1F is on the November 2026 ballot; the 2026 roll is the roll in place when voters decide. If the amendment passes, the first roll affected is the 2027 roll at the $150,000 step, followed by the 2028 roll at full $250,000 phase-in. When the 2026 and later rolls are certified, the analysis re-runs on the new data.

Ownership shares are measured on a residential-unit basis. The out-of-state ownership figure is a mailing-address proxy: it counts residential units whose owner’s mailing-address state in the roll is a non-Florida state or country. It undercounts true outside ownership — an out-of-state owner using an in-state LLC mailing address counts as Florida — and it does not prove where an owner actually lives. It is the cleanest available stand-in for second-home and out-of-state investor ownership of housing, not a definitive residency determination.

This read is a land-use-composition starting point. It is not a comprehensive fiscal, economic, or legal analysis, and it is not a substitute for a full planning or budget process.
